Hi everone,

I think I am not so far from the solution. I get the message :
"uploads/5p0il3r.jpg cannot be found."

So I think I have correctly bypass extension adding.

Now I'am trying to get in the parent directory, to get the image. I know there is a filter to remove ../, and i tried to write it in many way (url encoding), but i'am not bypassing the filter.

Can any one give me a hint ?

Friendly,
Asch.

It is hard to give a hint without telling the solution. But may that two helps:

- What would be the easiest way to get the "../" removed. Think about a php function that does it.

- You know what gets removed. May you can use that information now to create a valid injection. Or at least valid after the filter.

Use another null character instead of %00

yes atm the %00 is not working but there is still another way to bypass the appended file extension

I do not know what would be the right way to bypass it because I did not tried it yet.
But I found that one:
[url]http://security.stackexchange.com/questions/17407/how-can-i-use-this-path-bypass-exploit-local-file-inclusion
[/url]
Even when it is not the way to bypass the challange it is still interested

Greetings Folks!

I've used both type of null bytes to escape the filter and to strip .php but I still keep getting the following error:
<Spoiler Removed> cannot be found.

Can someone be kind enough to guide me? Am I looking inside the wrong directory?

There does exist a null byte that will work. Think escaping.
